django关于实现找回密码功能-----通过邮件来重置密码

1. 首先要调用发送邮件的函数，要成功的发送跳转地址，这里的跳转地址要储存在数据库中，以便以后可以知道是哪个账号要进行重置密码

from random import Random

from django.core.mail import send_mail
from users.models import EmailVerifyRecord
from MxOnline.settings import EMAIL_FROM


def send_register_email(email, send_type="register"):
    email_record = EmailVerifyRecord()
    code = random_str(16)
    email_record.code = code
    email_record.email = email
    email_record.send_type = send_type
    email_record.save()
    #上面是将验证码和email储存在数据库中
    email_title = ""
    email_body = ""
    if send_type == "register":
        email_title = "慕学在线网注册激活链接"
        email_body = "请点击下面的链接激活你的账号: http://127.0.0.1:8000/active/{0}".format(code)

        send_status = send_mail(email_title, email_body, EMAIL_FROM, [email])
        if send_status:
            pass
    elif send_type == 'forget':
        email_title = "慕学在线网密码重置链接"
        email_body = "请点击下面的链接激活你的账号: http://127.0.0.1:8000/reset/{0}".format(code)

        send_status = send_mail(email_title, email_body, EMAIL_FROM, [email])
        if send_status:
            pass

#随机生成验证码
def random_str(randomlength=8):
    str = ''
    chars = 'abcdefghijklmnopqrstuvwsyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'
    length = len(chars) - 1
    random = Random()
    for i in range(randomlength):
        str += chars[random.randint(0, length)]
    return str

2. views.py中书写俩个视图类其中一个为对发送的邮件的网址的解析
   其中html中还应该有form表单，然后是form表单跳转的页面，要判断密码是否修改成功
   这里注意一个为get一个为post

class RestView(View):
    def get(self, request, active_code):
        all_records = EmailVerifyRecord.objects.filter(code=active_code)
        if all_records:
            for record in all_records:
                email = record.email
                return render(request, 'password_reset.html', {"email": email})
        else:
            return render(request, 'active_fail.html', {})
        return render(request, 'login.html', {})


class ModifyView(View):
    def post(self, request):
        modify_form = ModifyPwdForm(request.POST)
        if modify_form.is_valid():
            pwd1 = request.POST.get('password1', '')
            pwd2 = request.POST.get('password2', '')
            email = request.POST.get('email', '')
            if pwd1 != pwd2:
                return render(request, 'password_reset.html', {'msg': '密码不一致', 'email': email})
            user = UserProfile.objects.get(email=email)
            user.password = make_password(pwd2)
            user.save()
            return render(request, 'login.html', {})
        else:
            email = request.POST.get('email', '')
            return render(request, 'password_reset.html', {'modify_form': modify_form, 'email': email})

    def get(self, request):
        return render(request, 'index.html')

3. 还要对url进行配置

    url(r'^reset/(?P.*)/$', RestView.as_view(), name='reset_pwd'),
    url(r'^modify/$', ModifyView.as_view(), name='modify_pwd'),

4. 这里注意这里视图类必须要两个，不可以合起来，因为第一个url在html中要携带参数，所以定义了俩个试图类
